[Bug 1687623] Re: linux-4.4.0-77.98 was a phased update in -updates only and may become partially installed (was: 4.4.0-77-generic breaks internet on 16.04.2)

[Andy Whitcroft]

The linux-4.4.0-77.98 was released to -updates only.  It appears that
this then lead to it being marked for phased updates.  The affected
people appear to have phased linux-signed only and not linux and linux-
meta.  This leads to linux-signed-image-4.4.0-77-generic (and its
dependencies) to be installed only.  This essentially leaves the user
with half a kernel with many drivers missing.  This leads to broken
internet and the like.

We have phased this update fully to avoid this occurring to any other
machines.  We have also changed the release process to prevent phased
kernel releases in the future.  I am creating an update-manager task as
this needs to be fixed as there are certainly other packages which could
trigger this behaviour.

update-manager should offer a correct fully phased update now once
booted into the previous kernel.  Also the "apt-get dist-upgrade"
solution is valid and will resolve the issue.

** Summary changed:

-  4.4.0-77-generic breaks internet on 16.04.2
+ linux-4.4.0-77.98 was a phased update in -updates only and may become partially installed (was: 4.4.0-77-generic breaks internet on 16.04.2)

Bug description:
  Hi as per title today I updated to  4.4.0-77-generic on my Lubuntu
  16.04.02 and wifi is not working anymore. When I click on the network
  manager I see "enable networking" (which is toggled) but no more the
  option about wifi.

  I reported this on ubuntuforum:
  https://ubuntuforums.org/showthread.php?t=2360216

  Where a user suggested to revert to an older kernel and see if this
  fixes the problem. I managed to revert to 4.4.0-75-generic via grub
  and everything works perfectly.

  Another user reported a similar issue caused by the same upgrade on
  the same system: https://ubuntuforums.org/showthread.php?t=2360215

  Can someone else confirm this bug?

  If you need more information I will be happy to provide it (I am a
  newbie though so please be patient).
